A highway accident can occur when a vehicle unintentionally drifts out of its lane and moves into the path of other traffic. Fortunately, several advanced driver assistance systems (ADAS) help to prevent this kind of incident. These include lane-departure warning, lane-keeping assistance, and lane-centering assistance. Audi's Active Lane Assist combines all three into one comprehensive safety feature.

The Audi Active Lane Assist system uses a camera mounted in the front of the rearview mirror that scans the road to detect lane markings and processes this data to determine if assistance is needed to keep the vehicle on course. There are three primary intervening functions of Audi Active Lane Assist to help keep a vehicle from drifting from its lane:
Although Audi Active Lane Assist will warn you with audible alerts, visual cues, haptic feedback, and subtle steering corrections when it appears you are approaching a detected lane marker and may leave the lane, you can always override the system with steering inputs. Ultimately, the driver has the final say on the vehicle's directional movement.
If you activate a turn signal before crossing a lane marking, Audi Active Lane Assist will not intervene in any way. The system will assume you are changing lanes intentionally. But suppose your vehicle has Side Assist and detects a car in your blind spot, even if you activate the turn signal. In that case, the system will initiate warnings and corrective steering.
You can turn Audi Active Lane Assist on or off by pushing the button at the end of the turn signal lever. When the system is on, the indicator lines in the gauge cluster will illuminate. White indicator lines mean the system has not yet met the conditions necessary to activate. This can occur if the road lanes are broken or interrupted, too wide, too narrow, too curvy, or the vehicle is not traveling at proper speeds.
Audi Active Lane Assist is intended for highway operation and fast-moving bi-ways, meaning speeds of 40 mph or higher. When the system's operational conditions are met, the indicator lines in the gauge cluster will turn green. It is now ready to provide warnings and feedback.
Beyond standard operation, you can configure Audi Active Lane Assist with individual lane settings using the car's Multi-media Interface, or MMI. Here, you can adjust steering timing and feedback. If you select "late," corrective steering occurs moments before the vehicle goes over the lane marker. When you choose "early," corrective steering happens continuously, keeping the car in the center of the lane.
You should not use Audi Active Lane Assist in certain weather and road conditions. The system may not operate properly in situations with limited visibility, worn lane markings, broken or missing pavement, or an obscured camera field of view.
Active Lane Assist is available across much of Audi's product portfolio.
